orderData and specifying columns with class names rather than column indices

orderData and specifying columns with class names rather than column indices

I'm trying to use orderData to sort via a hidden column. This works inside my columnDefs:

{ "targets": ['cleanup'],
"visible": true,
"searchable": true,
"orderData": [ 12 ]
},

However, I'd rather choose the sorting column based on its classname, such as

{
"targets": ['cleanup'],
"visible": true,
"searchable": true,
"orderData": [ 'cleanup-timestamp' ]
},

However, doing so gives me an Uncaught TypeError: Cannot read property 'sType' of undefined

Is it possible to indicate which column I'd like to use as sorting criteria given its th's classname, rather than column index?
